Battle Honours are emblazoned on succeeding units who have been accredited with their lineage deriving from 9 Australian Infantry Battalion A.I.F. This currently is 9 Battalion, The Royal Queensland Regiment (actually in recent times a combined unit 9/49 Battalion, the Royal Queensland Regiment).
WW1 Battle Honours are emblazoned on the unit's Queens Colour (the senior colour, as the monarch's colour - King or Queen, with precedence over the Regimental Colour, which displays the unit's WW2 battle honours).
There is an aberration to the above, in that the various units (Battalions) of The Royal Queensland Regiment all display common battle honours on their colours, those earned by units from that State. There is some additional inclusion of battle honours specific to the particular unit alone. Some examples to illustrate this are that all the battalions of The Royal Queensland Regiment display the battle honour "Landing at ANZAC", although earned only by 9 Australian Infantry Battalion A.I.F. (for Queensland units, with the other state Battalions of 3 Infantry Brigade). The colour also includes the battle honour "South Africa 1899-1900" - granted to all states units in recognition of the various states' contingents to the Boer War. None of them have lineage from those units.
Not all battle honours won by a unit are emblazoned on their colours, the number being limited. [Limits are 10 on each of the Sovereigns and Battalion Colours but in the case of 9RQR the addition of 'South Africa 1910' was granted to the Battalion Colour.
The current 9th Battalion The Royal Queensland Regiment also is custodian of the battle honours won by 9th Australian Infantry Battalion A.I.F. in WW1, and 2/9th Australian Infantry Battalion A.I.F. for WW2.
These include "Milne Bay" earned by 2/9 Australian Infantry Battalion AI.F., the first defeat of the Japanese on land in WW2.
